ARCHAEOLOGICAL EXCAVATIONS
Ancient Indian metallurgists made major contributions to the metallurgical history of the world. Archaeological excavations have shown that the Harappans were master craftsmen and had knowledge of copper metallurgy. They even manufactured bronze by mixing copper and tin. While the Harappans belonged to the Bronze Age, their successors belonged to the Iron Age. India produced highly advanced types of iron-forged iron, wrought iron and cast iron.

THE IRON PILLAR ON PILLAR
The iron pillar at Mehrauli, Delhi, is a remarkable example of the skill of Indian craftspersons. It is made of iron, 7.2. m high, and weighs over 3 tonnes. It was made about 1500 years ago. We know the date because there is an inscription on the pillar mentioning a ruler named Chandra, who probably belonged to the Gupta dynasty (Chapter 10(NEW EMPIRES AND KINGDOMS)). What is amazing is the fact that the pillar has not rusted in all these years.
